Abstract
Methods of forming a mirror by bonding a faceplate to a core structure using adhesive formulations that include fused silica particles having diameters that range between 1 to 60 micrometers with an average diameter of the silica particles being between 8 to 10 micrometers. The adhesive formulation further includes an activator including 25 to 50 weight % sodium silicate, 25 to 50 weight % sodium hydroxide and a liquid. The fused silica particles constitute 70 to 80 weight % of the adhesive formulation and the activator constitute 20 to 30 weight % of the adhesive formulation.
